Scientific title | Randomised, open-label study comparing the efficacy of antidepressant monotherapy and antidepressant combinations in the acute treatment of patients with resistant depression |
Study acronym | D-REZ-KOMB |
Study objectives | The aim of our study is to examine efficacy of antidepressant monotherapy and combinations of antidepressants in the treatment of resistant depression in common clinical practice. We will test the following null hypotheses: 1. That the reduction of depressive symptoms does not differ between monotherapy and combinations groups 2. The number of responders in both groups does not differ |
Ethics approval(s) | The Ethics Committee of Prague Psychiatric Centre approved on the 21st May 2008 |
Health condition(s) or problem(s) studied | Resistant depressive disorder |
Intervention | Patients will be randomly allocated to antidepressant monotherapy group or combination of antidepressant group. Specific antidepressant will be chosen by attending psychiatrist according to clinical judgment and with regard to the history of previous treatment. Antidepressant or combinations of antidepressant will be used in the dose cited in Summary of Products. Both interventions are defined as a new intervention not augmentation of previous antidepressant treatments. We will administer combinations that are commonly used in clinical practice. The total duration of treatment is 6 weeks. We will evaluate stability of outcome in responders after 2 months. |
Intervention type | Other |
Primary outcome measure | The change in the Montgomery-Asberg Depression Rating Scale (MADRS). Patients will be rated at baseline, week 2 week 4 and the end of acute treatment and responders after 2 month of treatment. |
Secondary outcome measures | Response to treatment that is defined as a greater than or equal to 50% reduction of MADRS score from baseline to the end of treatment. |
